ACL Bearings 8B745HN-STD H-Series Connecting Rod Bearing Set Narrowed 2.000" Small Block Chevy

The ACL Bearings 8B745HN-STD is a high-performance H-Series connecting rod bearing set designed specifically for Small Block Chevrolet engines with 2.000-inch journal diameter crankshafts. This narrowed bearing set is engineered for race and performance applications where precision and durability are critical.

Race Series Performance Features:

• Tri-metal construction with lead, tin, copper, and nickel alloy for superior strength and seizure resistance
• Hardened steel backing on all rod bearings to improve support and bearing retention
• High-strength overlay plate with reduced thickness for improved fatigue properties
• No flash plating on bearing backs to maximize heat transfer and improve grip in housing
• Increased eccentricity to compensate for bore distortion at high RPM and assist in hydrodynamic oil film formation
• Micron-tolerance machining for consistent wall thickness and crush
• Tight wall tolerances help maintain consistent clearances for reliable performance

Application:

• Small Block Chevy engines with 2.000" rod journal diameter
• Designed for forged crankshafts in race and high-performance street applications
• Narrowed design for specific engine builds requiring modified bearing width
• Standard size bearings for stock journal dimensions

ACL Race Series bearings are manufactured in Australia to exacting tolerances and are trusted by racers worldwide in applications from drag racing to road racing. The H-Series designation represents ACL's premier race bearing line, engineered to withstand the extreme conditions of high-RPM, high-load operation where standard bearings cannot survive.
